Petroleum and gas are found in sedimentary rocks such as shale, sandstone, mineral and dolostone.
At first there is sufficient gas pressure in the oil well to force out the oil. In time when it weakens oil can be forced out by injecting fluids or gases or by using pumps.
In the final the boards when the oil well pressure drops even more the oil is heated with steam or flooded with carbon dioxide or detergents to increase its viscosity and make it simpler to extract.
